Timon, from Plumstead, south-east London, will be sentenced on Thursday

On 1 January 2010, police saw him being restrained by his uncle as he shouted and screamed: “As soon as police leave I’m going to start f***ing fighting.”

Timon pleaded guilty to disorderly behaviour, but was next in trouble with the law on 26 May 2010 after attacking a woman outside a pub.

In a statement to police, the victim, who was a senior sales consultant, said she was talking to a group of three men, including a friend called ‘Jay’ when Timon pulled up in a car and said: “Why are you talking to that slag?”

“Trevor fully got of the car and began quickly walking towards me saying, ‘don’t talk to me’,” she said.

Timon called her a “w***e”, “crackhead” and “skaghead” throughout the incident and told her: “I’m going to bang you out.”

Tributes were left to Mr Dearlove after he died from the punch while out last year

Mr Griffiths said: “What were you hoping to achieve?”

The defendant replied: “Nothing. I was pissed off.”

He continued: “I was shocked. I didn’t think it was that serious. When I got the phone call (from one of the women) to say he was in hospital I was shocked to hear that. I could not believe my punch had led to hospital.”

Timon said he went to London City Airport and got on a flight to see his mother in Ireland.

After a couple of days, Timon said he returned and went straight to a police station with his father.

The court has previously heard Timon had “bad intentions” when he delivered a single powerful knock-out punch.

Mr Dearlove’s fried Andrew Cook gave evidence last week. He said: “There was this guy.

“I don’t know where he came from. He was just upon us all of a sudden. He came out of nowhere.

“He just started getting up in our faces. He started getting aggressive, shouting at us something like ‘Who the f*** are you?’

“He was very angry and agitated. He pushed me. He got really close to us pointing and shouting at us, being really abusive.

“He was looking for a fight. Not a nice guy. Trying to start a fight. We didn’t know why, it all happened so quickly.”

Timon had previously told jurors told jurors he punched the young banker after he was “laughed at” and called a “half chap”.

He will be sentenced after admitting manslaughter at the Old Bailey on Friday.
